Who should buy what
X-A7 (2019)
- You want an affordable first mirrorless with decent video capabilities
- You shoot a lot of selfie-style content or vlog on a budget

- You're considering a mirrorless upgrade from a DSLR
- Note: the X-T5 offers better resolution for stills — consider it if video is secondary
